AMD Radeon HD 6970M reviewed: major leap from HD 5870M, not quite a GTX 485M
What has 960 shaders, two gigabytes of dedicated GDDR5 memory with throughput of 115.2GBps, and the ability to churn 680 million polygons each and every second? Yes, the Radeon HD 6970M. AMD's fastest mobile chip to date has been doing the review rounds recently and the response has been unsurprisingly positive. Most modern games failed to trip up the 6970M even at 1920 x 1080 resolution, though the usual suspects of Crysis and Metro 2033 did give it a little bit of grief. All in all, the leap from the HD 5870M was significant, although NVIDIA's still relatively new GeForce GTX 485M has managed to hold on to its crown as the most powerful GPU on the mobile front. Benchmarks, architectural details, battery life tests (what battery life?), and value-adding enhancements await at the links below.
AMD launches Radeon HD 6000M series, endows them with HD3D and EyeSpeed skills
AMD might have let the Radeon HD 6500M and 6300M out a little early, but today marks the formal launch of its new, second-generation DirectX 11 mobile chips, the HD 6000M family. The new arrivals are the HD 6900M / 6800M in the gaming-centric high-end (offering up to 1.3 teraFLOPS of compute power), the HD 6700M / 6600M in the upper midrange, and the HD 6400M to provide mainstream users with all the discrete graphics loving that they desire. The 6000M range introduces AMD's new HD3D hocus pocus, which will allow apps, games and other media to present themselves in 3D to you -- provided devs care to make them so -- while EyeSpeed is a marketing name for a set of technologies designed to improve video streaming and gaming performance by taking on more tasks with the GPU. You'll care about that if you're a big online media consumer and you'll also want to know that AMD has an exclusive on hardware acceleration for DivX video. Full press release awaits after the break.
2011 to bring 200 PCs combining GeForce GPUs and Sandy Bridge, first laptops to be quad-core
What's NVIDIA got up its sleeve for CES, you ask? A whole host of Sandy Bridge laptop and desktop machines, by the sound of its latest press release. The green giant of graphics has proudly announced a new record of 200 OEM design wins for Intel's incoming CPUs. The big draw of Sandy Bridge is that it's the first processor to include an integrated GPU embedded directly within its die, which is projected to improve power efficiency and overall performance -- though clearly it hasn't been impressive enough to get PC vendors to abandon discrete graphics chips. If anything, they seem to be going in the other direction and insisting on a discrete GPU as well. In other news, whether with or without NVIDIA's help, the first Sandy Bridge laptops will feature quad-core parts. Such is the word directly from Intel, with one insider adding that the dual-core debutants will get their chance a month after CES, around the middle of February. Skip past the break for NVIDIA's boastful PR or hit the source for more on Intel's plans.
NVIDIA outs 300M mobile graphics series, causes little excitement
Many a mind might've strayed from all the CES crazy-talk about future tech and wondered as to what exactly is going on in the war against bad graphics on otherwise totally sweet laptops. The answer from NVIDIA is, disappointingly, not much. The green giant of GPUs quietly snuck out its 300M mobile GPUs over the turn of the year, and there was good reason for the lack of fuss -- the top tier GeForce GTS 360M sports the same number of processing cores as its 260M predecessor, accompanied by the same 2GHz memory clock and identical 128-bit memory interface. But don't despair yet, sailor! There's the stark omission of any GeForce GTX models among the new 300Ms, which should fuel hopes that this gap in what NVIDIA calls the enthusiast market will be filled by Fermi-shaped chips come March of this year.
Sony finally admits NVIDIA chips are borking its laptops, offers free repair
Last summer, while Dell and HP were busy pinpointing and replacing faulty NVIDIA chips in their notebooks, Sony was adamant that its superior products were unaffected by the dreaded faulty GPU packaging. Well, after extensive support forum chatter about its laptops blanking out, distorting images and showing random characters, the Japanese company has finally relented and admitted that "a small percentage" of its VAIO range is indeed afflicted by the issue. That small percentage comes from the FZ, AR, C, LM and LT model lines, and Sony is offering to repair yours for free within four years of the purchase date, irrespective of warranty status. Kudos go to Sony for (eventually) addressing the problem, but if you're NVIDIA, don't you have to stop calling this a "small distraction" when it keeps tarnishing your reputation a full year after it emerged? [Thanks, Jonas]
All NVIDIA 8400M / 8600M chips faulty?
NVIDIA's stock took a pretty big hit last week when it announced that "significant quantities" of "previous-generation" GPUs and mobile and communications processors were defective and that it would take a $250M charge against earnings to repair and replace the affected chips, but the company didn't say which chips specifically were faulty, nor how many. That might be because the problem is much worse than it even sounds -- according to a report in The Inquirer, every single G84 and G86 GPU in the 8400M and 8600M series of cards is affected. Apparently both chips share an ASIC, and the core design suffers from the same heat-related issues. That certainly implicates a "significant quantity" of chips, all right, but this is just a rumor for now -- one that's probably best handled by NVIDIA stepping up and letting its customers know exactly how big the problem is.[Thanks, Rich]
NVIDIA says "significant quantities" of laptop GPUs are defective, stock tumbles
If you're the type to watch the late stock tickers, you might have noticed that NVIDIA's stock just took a pretty big hit, down 24 percent to $13.56 -- that's because the company just informed investors that "significant quantities" of previous-generation graphics chips have been failing at "higher than normal rates," and that it's lowering its Q2 estimates due to pricing pressure. NVIDIA will be taking a $150M to $250M charge against earnings next quarter to cover the cost of repairing and replacing the affected chips, but didn't specifically announce what products were defective, just that they include GPUs and "media and communications processors." Laptop makers have apparently already been given an updated GPU driver which kicks in fans sooner to reduce "thermal stress" on the GPU, and NVIDIA says it's talking to its suppliers about being reimbursed for the faulty parts. That's great and all, but we'd really rather know which chips specifically are failing -- if you're serious about playing in the big leagues, you better come clean, guys.
